Tell us a little about you. What cars you are interested, where you are from and why you are interested in learning to tune.
I'v got an RX7 FD series6 13b rotary fitted with a T04z single turbo and an Apexi Power FC,i took the starter package so dat i can try and tune it on my own wit yal help of course;)
Welcome on board!
The TO4Z is a pretty good option for a 13B street car and I've tuned a few over the years. They offer great power potential with reasonable boost response. Is your engine still stock or have you had it rebuilt? Porting makes a huge difference to the power these engines make and the stock seals are not ideally suited to high boost.
Welcome to the forum. Rotary's are one engine I've yet to tackle, let us know how you get on with it
